我不使用Anaconda.清理python 3.5.2和pip3.
Im not using Anaconda. Clean python 3.5.2 and pip3.
有人知道是什么问题吗?
Does any one know what the problem is?
推荐答案
降级到龙卷风5.1.1将解决该问题.当您使用pip3
Downgrading to tornado 5.1.1 will solve that problem.As you are using pip3
sudo pip3 uninstall tornado
sudo pip3 install tornado==5.1.1
